ABSTRACT
During 1998, the emphasis of our activities was focused mainly on target
fabrication. Successful conversion requires a reliable irradiation target; the target being
developed uses thin foils of uranium metal, which can be removed from the target
hardware for dissolution and processing. This paper describes successes in (1) improving
our method for heat-treating the uranium foil to produce a random-small grain structure,
(2) improving electrodeposition of zinc and nickel fission-fragment barriers onto the foil,
and (3) showing that these fission fragment barriers should be stable during transport of
the targets following irradiation. A method was also developed for quantitatively
electrodepositing uranium and plutonium contaminants in the 99Mo. Progress was also
made in broadening international cooperation in our development activities.The submitted manuscript has been created by the
